Abstract

Optically active enantiomers of the formula I ##STR1## where R is a group of the formulae ##STR2## R 1 and R 2 , among others, are halogen or CF 3 and Z is a carboxyl, carboxylate, carboxylic acid ester, thioester, carbonamide, carboxylic acid anilide, carbohydrazide or thioamide group, are interesting herbicides the effect of which is considerably superior to that of the optically inactive racemates.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. Compound of the formula ##STR84## 
     
     
       2. Compound of the formula ##STR85## 
     
     
       3. Compound of the formula ##STR86## 
     
     
       4. Compound of the formula ##STR87## 
     
     
       5. A herbicidal composition comprising a herbicidally effective amount of a compound as defined in claim 1 and a carrier therefor. 
     
     
       6. A method for combatting the growth of weeds which comprises applying thereto a herbicidally effective amount of a compound as in claim 1. 
     
     
       7. A herbicidal composition comprising a herbicidally effective amount of a compound as defined in claim 2 and a carrier therefor. 
     
     
       8. A method for combatting the growth of weeds which comprises applying thereto a herbicidally effective amount of a compound as in claim 2. 
     
     
       9. A herbicidal composition comprising a herbicidally effective amount of a compound as defined in claim 3 and a carrier therefor. 
     
     
       10. A method for combatting the growth of weeds which comprises applying thereto a herbicidally effective amount of a compound as in claim 3. 
     
     
       11. A herbicidal composition comprising a herbicidally effective amount of a compound as defined in claim 4 and a carrier therefor. 
     
     
       12. A method for combatting the growth of weeds which comprises applying thereto a herbicidally effective amount of a compound as in claim 4.
